To all 'whom t may concern.' i

Be it known that l, Enwnnn AUGUST Koor, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have"V 'invented certain new and useful Improvements in Bottle-Stoppers, of which Athe `following is a specification. v

My invention relates to improvements in bottle stoppers, and has particular reference to improvements in bottle Stoppers of 'the t ipe which seals the bottles against the entrance of liquid or Vany other substance.

@ne of the objects of my invention is to provide an improved device of this character which will, be simple, durable and reliable in construction and effective and eilicient in operation.

YGther objects of my invention will appear hereinafter. Y

Referring to the accompanying drawings: ligure l is a view in eleva-tion of the neck portion of a bottle or receptacle sealed by an improved stopper embodying my invention. Fig. 2 is a vertical section through the stopper and neck of the bottle. Fig. 3 is a transverse section on the line 3--3 of Fig. 2, and Fig. e is a transverse section on the line Ll-l of Fig. 2.

ln the drawings, which illustrate one enibodiment of my invention, I have shown a stopper or closure device adapted to belinserted in the neck or opening of a bottle or receptacle for the purpose of permitting the original contents of the bottle to be removed and for preventing the refilling of the bottle.

ln `Figs. l and 2 l have shown the neck portion ik of a bottle of usual construction, and this may be regarded as representative of any type of bottle desired to be used. rhis bottle, of course, has a hollowtubular shaped neck communicating with the interior of the bottle and open at its upper end. ln the upper end portion of the bottle the stopper B is inserted for sealing the neck opening against the entrance of fluid or liquids into the bottle. This stopper may be of any suitable construction for the purpose. ln the form of stopper of this kind. This tubular member or stopper has a continuous passage eXtending throughout its length and open at both ends. The lower end 2 of this passage communicates directly with the interior of the neck and thence to the interior liquid to passdrawings l have shown one v of the bottle. lThe upper end portion 3 of this passage is constructed so as to receive cork l. Between the upper "bers 5 and G which communicate with each other through a port 7 which is of less diameter than the diameter of the chambers and is formed by means of an annular internal rib or flange 8. These chambers 5 and 6 are occupied by cheek valves 9 and l0 respectively and these valves are constructed so they have some play within their respective chambers. They are constructed so that they serve to close the port 7 and the inner end 2 of the passage so as to prevent the entrance of liquid into the bottle; rEhe seat for the upper valve 9 is formed by the internal flange or rib 8 while the seat for the lower valve l0 is formed by the internal rib or flange 1l which forms the inner or lower end 2 of the passage through the stopper. These valves are loose and free in their respective chambers but when the bottle is set upon its bottom in normal position the valves seat themselves by the action of gravity and any attempt to Dass liquid o-r push the stopper into the bottle will be prevented by said valves. lil/hen, however, the bottle is turned in a position to pour liquid from the bottle, gravvity and the flow of liquid from the bottle act to unseat the valves and thereby permit the through the passage of the stopper. ln the construction shown the stopper or tubular member l and the valves 9 and l0 'are preferably made of some hard compact and solid material, such as porcelain or glass. The stopper is enlarged in diameter at its upper end or head to form a flange or shoulder 12 which abuts the end of the neck of the bottle and prevents the stopper from being forced into the bottle. ln the construction shown it is customary to fill the bottle with liquid, insert the stopper B in the bottle., place the cork Ll in the upper end portion 3 of the stopper passage and Vthen firmly securing or fastening the stopper in`the neck of the bottle so that it cannot be removed and thus open the neck of the bottle.

In order to prevent unscrupulous persons from removing the stopper and using or refilling the bottle after its original contents have been removed, l provide means for interlocking the neck of the bottle and llO -form of a split ring and is made of Itis adapted to expand into a groove Y 18 in the neck of the bottle but this groove 18 such manner that shown as being circular in tle useless. groove 18 in` the neck of the bottle and a similar groove 19 in the periphery of theV stopper member B. These two grooves orV recesses are adapted to reg'ister when the stopper is inserted in its proper position in" the neck of the bottle. In these registering grooves or recesses I provide a ring or annulus 2O of metal. This member 20 is in the spring metal.

is sufliciently deep so that part of the ring occupies the groove 19 in the neck of the stopper member terlock the stopper and neck of the bottle in the stopper cannot be removed except by breaking the neck of the bottle, and of course once the neck of the bottle is broken the bottle is renderedV useless. In assembling these parts the split spring ring 2O is placed in the groove 19 of Ithe stopper member B and compressed or contracted in diameter so that it and the stopper maybe forced into the neck of ,the bottle and as soon as the two grooves 18 and 19 register the ring will expand of its own elasticity and occupy the position shown in Fig. 2, thereby locking these parts.

In the drawings the locking ring 20 is section and the grooves 18 and 19 correspondingly formed but it is obvious that this ring may be of any suitable shape in section and the grooves 18 and 19 of corresponding shape.

In order to seal space between the stopper B and the neck of the bottle I reduce the lower portion of the periphery of the stopper so as to provide a comparatively large space between the interior surface of the neck of the bottle and the stopper and in this space I provide a packing 17. This may be of any suitable substance for the purpose. I prefer, however, to use cork. The cork may be in the form of a single ring of suiii- .cient heightor it may be of a number of smaller rings, as shown in Fig. 2, so that the gasket or packing will be laminated, in a sense. This eectively seals the space between the stopper and the neck of the bot- Gapies 0f this patent may be obtained for ivc cents each, by addressing the Commissioner of Patent. Y Washington, D. 1. Y

It willA be obvious to one skilled in the art that my invention is capableof modification without departing of the'invention.
